Vacuum canister with auxiliary intake valve
First Claim
1. A vacuum canister for use in a central vacuum system, said vacuum canister comprising:
- a housing having a dirt collection chamber and a clean chamber separated from the dirt collection chamber, whereby a hole extends through said housing into the clean chamber;
a wall extending intermediate the clean chamber and the dirt collection chamber of the housing, whereby said wall further defines an aperture that connects the dirt collection chamber to the clean chamber;
an auxiliary vacuum intake assembly disposed within the clean chamber, a first part of said intake assembly being mounted within the hole formed in the housing and a second part of said intake assembly being mounted within the aperture in the wall, the first and second parts being in communication with each other so that air may flow from the first part through the second part and into the dirt collection chamber;
a vacuum pump assembly housed within the clean chamber; and
electrical wiring connecting the auxiliary vacuum intake assembly to the vacuum pump assembly.

Abstract
A vacuum canister for use with a central vacuum system is disclosed. The vacuum canister includes a hollow, tubular housing that has openings at either end. A cover covers the upper opening and a dust collection bin is disposed beneath the lower opening. The housing is divided into clean and dirt collection chambers by a wall. The clean chamber is a dust-free area and the vacuum pump assembly is mounted therein. The dirt collection chamber is the area in the canister where the dirt-laden vacuumed air is drawn into the device. The vacuum canister is provided with an auxiliary vacuum intake assembly that enters the housing in the clean, dust-free chamber. The intake assembly includes a receptacle for receiving the end fitting of a portable vacuum hose and the receptacle is operatively connected to the dirt collection chamber of the housing by way of a conduit that extends from the receptacle through an aperture in the wall and into the dirt collection chamber. The receptacle is wired to the motor for the vacuum pump assembly so that when the portable hose is attached to the receptacle, the vacuum pump is automatically started. The wiring for the receptacle passes through the clean chamber of the housing. The receptacle includes a pivoted cover which covers the receptacle when it is not in use so as to maintain the vacuum within the system.

17. A vacuum canister for use in a central vacuum system, the system having at least one receptacle adapted to receive a portable vacuum hose, the receptacle being connected to the canister by at least one conduit, the canister having an exhaust pipe exiting therefrom for exhausting cleaned air from the system;
- said vacuum canister comprising;
a housing having an upper end and a lower end, the upper end defining a first opening and the lower end defining a second opening, the housing further defining at least one hole therein, the hole being proximate the upper end of the housing; a cover disposed over the first opening; a dust collection bin disposed under the second opening; a wall disposed between the upper and lower ends of said housing, said wall having an upper surface proximate the upper end of said housing and a lower surface proximate the lower end of said housing, whereby a clean chamber is formed between said upper surface and said upper end, and a dirt collection chamber is formed between said lower surface and said lower end;
wherein said wall further defines a bore and an aperture that each connect the clean chamber to the dirt collection chamber;a vacuum pump assembly including a motor for generating a vacuum in the system, the vacuum pump assembly being disposed within the clean chamber and proximate the bore in the wall, whereby said pump assembly causes air to be suctioned from the dirt collection chamber to the clean chamber through the bore; a filter support extending from the lower surface of the wall and into the dirt collection chamber, said filter support being proximate the bore so that air is suctioned through the filter as it moves toward the bore; an auxiliary vacuum intake assembly disposed within the clean chamber, a first part of said intake assembly being mounted within the second hole in the housing and a second part of said intake assembly being mounted within the aperture in the wall, the first and second parts being in communication with each other so that air may flow from the first part, through the second part and into the second chamber.
